CNN reports that a single shooter, who has been identified as 64-year-old Stephen Paddock of Mesquite, Nev., was positioned in a hotel room on the 32nd floor of the Mandalay Bay Resort and Casino and shooting from above the crowd, gathered outside Mandalay at Las Vegas Village. He has been killed, either as police raided his hotel room or by a self-inflicted injury.

"Gun shots were ringing off of the stage rigging and road cases," Owen said at about 4:15AM ET. "No one knew where to go ... Thank you LVPD and responders for keeping us safe."
